In a troubleshooting method, a controller first determines that a fault occurs on a first multi-layer link passing through a first port on a first network device, where the first multi-layer link is a link in a link aggregation group between the first network device and a second network device. The controller then releases an optical layer resource of the first multi-layer link, and deletes the first multi-layer link from the link aggregation group. The controller further establishes, a second multi-layer link for restoration of the first multi-layer link, based on a first idle port on the first network device and a second idle port on a target network device, and adds the second multi-layer link to a target link aggregation group between the first network device and the target network device.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The method according to claim 1, wherein the different types of networks spanned by the first cross-layer link and the second cross-layer link includes an optical network and an IP network.
7. The method according to claim 3, wherein the target network device is the second network device, the first idle port is a port on the first network device, and the second idle port is a port on the first multi-layer link.
8. The method according to claim 4, wherein the target network device is a third network device, the first idle port is the first port, the second idle port is a port on the third network device.
10. The method according to claim 9, wherein the target network device is the second network device, the first idle port is the first port, and the second idle port is a port on the second network device.
15. The controller according to claim 11, wherein the different types of networks spanned by the first cross-layer link and the second cross-layer link includes an optical network and an IP network.
17. The controller according to claim 13, wherein the target network device is the second network device, the first idle port is a port on the first network device, and the second idle port is a port on the first multi-layer link.
18. The controller according to claim 14, wherein the target network device is a third network device, the first idle port is the first port, the second idle port is a port on the third network device.
20. The controller according to claim 19, wherein the target network device is the second network device, the first idle port is the first port, and the second idle port is a port on the second network device.
24. The non-transitory computer-readable storage media according to claim 21, wherein the different types of networks spanned by the first cross-layer link and the second cross-layer link includes an optical network and an IP network.
